Description OSIDB Bzimport 2026-11-11 18:41:29 UTC 
sync-rpc runs asynchronous commands synchronously by putting them in a separate proces. Prior to version 1.3.7, if an attacker could guess the correct port and it was not blocked via a firewall, it was possible to load and execute arbitrary JavaScript files stored on the server running sync-rpc. This issue has been patched in version 1.3.7.
